=46rom the documentation of 'load'[1]:

"In no circumstance will any local variables in the loaded file be =
propagated to the loading environment."

There are other, better ways to do this for example by separating your =
logic into classes and then get the program going from a small main =
program. Any tutorial about moderately complex ruby programs should =
illustrate how to do this.

As you indicated, I put my classes in files and then require'd, them and
it works, of course.

I guess as I attain experience, the seeming restrictive way that
"require" works, will seem great. I was naive in thinking that arbitrary
code could be "include"-ed.

Best Regards
Steve.
